September 2019 hottest on record globally, second hottest in U.S. history – All-time record for 12-month rainfall in U.S.

5 October 2019 (Copernicus Climate Change Service) – In Europe, temperatures were above average over most of the continent, especially in the south and south-east. Below-average temperatures occurred over much of Norway and Sweden, and over the far east of the continent. Globally September 2019 was 0.57°C warmer than the average September from 1981-2010, making […]

Swiss glacier volume reduced by 10 per cent in only five years – More than 500 small glaciers have vanished – Over the past 12 months, two percent of total Swiss glacier volume lost

15 October 2019 (Swiss Academy of Sciences) – During the summer heatwaves of 2019, glacier melt rates reached record levels. This led to another year of major losses of ice volume, as reported by the Cryospheric Commission of the Swiss Academy of Sciences. Switzerland’s glaciers have thus shrunk by 10 per cent over the past […]

Authoritarian advance: How authoritarian regimes upended assumptions about democratic expansion – “These regimes are turning the tools of coercion outward to push back on democracy”

By Laura Rosenberger 13 September 2019 (GMF) – Thirty years after the fall of the Berlin wall, democracies again face a struggle against authoritarianism. This is not the ideological battle of the Cold War, but it is a confrontation between systems of government. As democracies are showing cracks and as authoritarian regimes are gaining strength, […]

The sea is running out of fish, despite nations’ pledges to stop it – Major countries that are promising to curtail funding for fisheries are nevertheless increasing handouts for their seafood industries

By Todd Woody 8 October 2019 (National Geographic) – As global fish stocks that feed hundreds of millions of people dwindle, nations are scrambling to finalize by year’s end an international agreement to ban government subsidies that fuel overfishing. Yet as negotiations at the World Trade Organization resume this week in Geneva, Switzerland, new research shows that governments have […]

Thousands of ships fitted with “cheat devices” to divert poisonous pollution into sea – “In the North Sea and some parts of the Channel, the water quality has already been heavily degraded”

By Wil Crisp 30 September 2019 (The Independent) – Global shipping companies have spent billions rigging vessels with “cheat devices” that circumvent new environmental legislation by dumping pollution into the sea instead of the air, The Independent can reveal. More than $12bn (£9.7bn) has been spent on the devices, known as open-loop scrubbers, which extract […]

More than half of Europe’s endemic trees face extinction – “This report shows how dire the situation is for many overlooked, undervalued species that form the backbone of Europe’s ecosystems”

GLAND, Switzerland, 27 September 2019 (IUCN) – Over half (58 percent) of Europe’s endemic trees are threatened with extinction, according to assessments of the state of the continent’s biodiversity published today by the International Union for Conservation of Nature (IUCN). The introduction of invasive species, unsustainable logging and urban development are key threats causing the […]

Record heatwave and extreme drought reveal lost “Spanish Stonehenge”

By Kasha Patel 19 September 2019 (NASA) – In 1963, the Spanish government under Francisco Franco built the Valdecañas Reservoir in order to bring water and electricity to underdeveloped parts of western Spain. However, the creation of the reservoir flooded some inhabited areas as well as large stone (megalithic) monuments. After fifty years underwater, one […]

Munich Re: Climate change and its consequences – 18 of the 20 warmest years are in the period 2001-2018

By Dr. Eberhard Faust and Ernst Rauch 8 August 2019 (Munich Re) – When temperature records are broken or major weather disasters strike, people ask whether climate change has anything to do with it. One thing is clear: individual events themselves cannot be attributed directly to climate change. One needs to look at overall trends. […]

Earth warming more quickly than thought, new climate models show – “We have better models now. They have better resolution, and they represent current climate trends more accurately.”

By Marlowe Hood 17 September 2019 (AFP) – Greenhouse gases thrust into the atmosphere mainly by burning fossil fuels are warming Earth’s surface more quickly than previously understood, according to new climate models set to replace those used in current UN projections, scientists said Tuesday. By 2100, average temperatures could rise 7.0 degrees Celsius above […]

Summer 2019 in the Northern Hemisphere tied for warmest summer on record – Five hottest NH summers have occurred in the past five years

By Andrew Freedman 16 September 2019 (The Washington Post) – The Northern Hemisphere just had its hottest summer on record since 1880, according to National Oceanic and Atmospheric Administration data released Monday. NOAA found the average global surface temperature taken by thousands of thermometers, buoys and other sensors on land and sea tied with that of 2016 […]
